TOASTER-TRAY BUTTON.

Appnaton ,sled april e,

My invention relates to electric table cooking devices and particularly to electric toast# ers.

The object of my a relatively simple, ufactured, and for operating tric toasters.

ln practicing my invention l provide a me comprising a base andside and ns, in which a plurality of trays are mounted to have a turning movement relatively to the traine and to a heating element supported between the side frames in the base. rihe side portions ot each ot the trays are provided with openings through which one end ot a tubular member may extend rlhe other end 'f the tubular member is provided with a serrated edge that is adapted to engage, and interlock with ar knob or button.

A machine bolt extends through the but ton, the tubular member and a spring washer that engages the outer flat surface of the button. The nut mounted on the inner end ot the machine bolt is held in its proper operative position relatively to the bolt by projectionsintegral with the side portions of the trays to prevent turning movement thereoi1 relatively to the bolt.

Fig. etis a view, in side elevation, of a tubular member comprising` a part ott the device embodying my invention and,

F ig. 5 is a developed view of the member illustrated in Fig. d.

An electric toaster 11 comprises a base 12, consisting' oitl a stamped, shee-tmetal plate having a top portion and a plurality of integral depending flanges 13. Each of the flanges 13 islprovided with integral end portions 14 extending angularly relatively to the flanges 13 and located in the same plane, and a plurality of supporting means 15 ot a suitable heat-insulating material are invention is to provide inexpensive, easily maneasily assembled mechanism the reversing trays of elecpending application,

secured against the end portions adjacent the inner suri'ace thereof. The construction of the base and of the end portion is more particularly disclosed and claimed in my co- Serial No. 630,271, tiled April 6, 1923, and assigned to the W. E. S: M. Co. (Case 10241), to which application reterencemay be had ot' construction.

A plurality or' vertically extending side `tiames 16 (av portion of which is illustrated in Fig. 2) are mounted on they top of the base 12 and are suitably secured thereagainst. A vertically extending heating element 1T comprises a plurality of sheets of Vinsulating material, such as mica, upon which a resistor (not shown) is mounted.

it plurality of trays 18 having integral and laterally-extending side portions 19 are provided and are pivotally mounted in the side trames 16 in a manner-to be hereinafter set forth in detail. Reference may be had o the hereinbetore mentioned application or -further and more complete details of construction ot these parts of the device. which are not here illustrated nor described in detail as they form no part of my present invention.

Each of the side frames 16 is provided with openings v21 extending therethrough adjacent the outer edges thereof just' above the bottom edge of the frames. Each .of the side portions 19 of the trays 18 .is profor further details i vided with a substantially Vcircular opening 22 therethrough. 'Portions 23 of the sides 19 are punched outwardly immediately adjacent the openings 22, thetwo portions 23 being located `on a diametral'line of each ot the openings 22, whereby an opening is provided in each of the side portions 19 that is irregular in contour and comprises a substantially circular portion having two eX- tensions.

A tubular member 24k comprises a1 punched piece ot sheetmetal that is provided with a serrated outer edge 25 and two integral, longitudinally-extending llugs 26 that are so spaced as to be located on a diametra-l line when the sheet is rolled up to substantially tubular form, as illustrated more particularly in Fig. 4 of the drawing. The member 2i constitutes a tubular bearing-member and support for one end oit a tray 18 and eX- tends through, and has a loose fit in one of the openings 21 in the side frame 16. A

Q75* 'to'.the tray 18 is prevented.

molded knob 27 of a suitabley heat-insulating material and of any suitable or desired contour is located in close operative engagement with the serrated edge 25, with which serrated edge the inner surface ofthe knob or button 27 is adapted to interlock;

A spring washer 28 is provided adjacent to the outer surface of the knob '27 and a Atray pivotally mounted in said frame, and

machine bolt 29 extends through a suitable opening in the knob 27 and through the tubular membery2, and is of such a length as to extend through'the opening 22 and slightly therebeyond. lA hexagonal nut 3l has screw-threaded engagement with the inner end ofthe machine bolt 29 and the distance between the integral inturned portions 23 is such as to permit the nut 31 to bey located between the portions 23 and to fit substantially tightly to prevent a turning movement of the nut 3l relatively' tothe machine bolt 29. l f j Y The deviceembodying my invention provides a tubular bearing member'of relatively large external diameter whereby the wear is Y reduced to a minimum. The integral projections 26 on the tubular member 24 are adapted to tit into the openings left by punching out the integral. inturned portions 28 to the eectl that the tubular member 2t may be interlocked with the trays and, therefore, maintain its position relatively thereto under all conditions of operation. The serrated edge`25 of the tubular member 24 is forced'into the relatively soft materialof the knob 27 whereby these two members Lare interlocked' and a turning movement of'one relatively to the other is pre-y vented.

The members 28 fit closely on'each side of a nutV 3l, thereby causing an interlocking of these parts whereby relativeemotion of the nut relativelytothe bolt 29, and therefore motionof the entire tray operatingstructure, comprising the tubular member 24, washer 28, and bolt29, relatively The spring washer 28 compensates Yfor changes mayoccur'in the thickness of the I knob 27 in case-this should shrink, after being subjected to the heat of the toaster.

' This washer Vis also of value during the assembly ofthe device, as slight inaccuracies in the relative positions o f the nut 31, bolt 29 and of the knob 27 with respect to the tubular member 24- are easily compensated thereby. n

Various modifications and changes may be whatever Y memes prior art.

I claim as my invention: l. In a toaster, in combination, a frame, a

means for'pivotally supporting and actuating said tray comprising a tubular meniber extending through said' frame, a button operatively engaging one end of said tubular member, and means for holding lsaid tubular member at one end only against said tray. n

2. VIn atoaster, in combination, a frame, a tray, a tubular tray and interfitting with said frame for pivotally supporting said tray therein, actuating means operatively .engaging one end only of said tubular member and interlocked therewith, and'means having a. portion interlocked with said tray for'holding said tubular member and said actuating means against said tray. Y

In a toaster, in combination, a frame, a trayhaving an opening of irregular contour in the side portion thereof, atubular ymember having one end operatively engag? ing saidy side portion at said opening and having 'integral' extensions located in portions of said opening and extending through said frame for pivotally supporting the tray therein, and a knob spaced from said. tray by.r and operatively engaging the other end of said tubular member and interlocked therewith to effect turning movements of said tray.

4. In a toaster, in combination, a frame. a tray having an opening of irregular contour in the: side yportion thereof, a tubular member having one end operatively engaging said, side portion at said opening and having integral extensions located in portions of said opening and extending through said frame for pivotally support-ing the tray therein, a knob interlocked with the other end of said tubular member, a bolt Vextending through said knob and tubular member and a nut on said bolt operatively engaging the side portion of said tray and inter- "locked therewith.
